What's hot and in a red bikini?? And at Wet Republic?? WHO??

Holly Madison spent her 4th of July basking in the Vegas sun with “Holly’s World” castmates Josh Strickland and Angel Porrino at WET REPUBLIC, hosted by Ciroc. The gorgeous star of PEEPSHOW arrived at the MGM Grand hotspot looking glam in a floor-length Roberto Cavalli leopard-print dress. “I’m really excited to celebrate 4th of July at WET REPUBLIC. I brought all my friends, I love this pool and I’m ready to jump in the water and get in my bikini,” Holly said on the red carpet.

The self-proclaimed workaholic revealed that her love life has slowed as she has “a really hard time meeting guys because I’m so busy, but someday [I’ll meet someone]. I’m definitely open to it.” The Las Vegas starlet said, “I love filming ‘Holly’s World’ and I love doing PEEPSHOW here in Las Vegas. I’m writing a book about Las Vegas as well, so I’m keeping busy with those things and we’ll see what’s next.”

Friend and castmate Angel arrived to the ultimate daylife destination in an off-the-shoulder black cover-up revealing for the first time her generous 21st birthday present from Holly in a red peace-sign stamped bikini. Castmate and co-star of PEEPSHOW Josh looked the part of California beach boy in a tank top, neon yellow sunglasses and crimson bathing suit, and playfully showed off his “Situation” to onlookers.

Always supportive of her new home, Holly attended the UFC 116 battle at MGM Grand the night before. “The UFC fights are just the most exciting events in Las Vegas. There’s always something happening every second at one of the mixed martial arts fights. [With] the gatherings of all the fans and everything, it’s just a great energy,” Holly gushed from her VIP bungalow.

The friends cheered as Holly stripped down to a bright red bikini showing off her American pride. The blonde bombshell divulged that her bikini secrets are simply to eat lots of fruit the day before and never forget a spray tan. Holly immediately made her way to the WET REPUBLIC waterfall and sexily posed for hundreds of ecstatic fans. Holly waved an American flag and soaked up the unrivaled holiday atmosphere at the red, white and blue-decked ultra pool.

Holly and friends enjoyed WET REPUBLIC’s festive Strawberry Margarita Cocktail Push-ups, served by patriotic bikini-clad cocktail servers, as they cooled down in the exclusive VIP dipping pools and mingled with fans. The trio danced to summer hits like Katy Perry’s “California Girls” spun by DJs Echo and Nathan Scott.
